Hi everyone , don't know if anyone knows anything about this lens but i found it amongst some old gear and have given it a go and it doesn't seem to bad in some situations






no cropping on the images just adjusted light
what do you think ?

In low resolution almost any lens looks good, please provide crops on central part and at the edges. I think in advance this is an average lens.

Thats a Tamron model 680 with matched teleconverter -

http://translate.google.com/translate?hl=en&sl=ja&u=http://www.tamron.co.jp/data/old-lens/olm135f2_8.htm

One of the first generation of Tamron T-mount lenses, and in fact one of the first T-mount lenses.

Under the regular Tamron brand the set was also sold as a "Duo-Tamron"

I have this lens, without the teleconverter, as a Soligor.

Its quite a decent lens I think. It would probably be better without the teleconverter. The T-mount should unscrew off the end, and should go on the lens proper after you unscrew the TC, making it a 135/2.8 instead of the 225mm/5.5 with the TC on.

I know Hanimex sold the set, but I wonder what other Tamron models were sold by Hanimex. Its a good alternative line of investigation as I am collecting these early Tamrons. Thanks for the tip !

That's absolutely correct, luis.

I've got this lens and it performs very well as a 135mm but it's horrible with the converter.
Anyway it's nice to use and has a beautiful diaphragm shape.
